pressure relief valve and its installation.
Orientate the outlets of the hot water Tee (21) and temperature pressure relief valve (1) toward the rear
of the tank and away from the electrical cover. The hot water pipe work and drain line from the hot water
Tee (21) and temperature pressure relief valve (1) must not be installed in front of or prevent access to
the electrical cover of the water heater.
A union (19), olive (18) and compression nut (17) are supplied for the connection of the drain line to the
temperature pressure relief valve (1). Refer to
requirements of the drain line.
Olives (18) and compression nuts (17) are supplied for the connection of the hot water pipe to the hot

Notes
•
Penetrations through the roofing material are to be:
➢
at the high point of the roof tile or metal sheet;
➢
made neatly and kept as small as practicable;
➢
waterproofed upon installation of the hot and cold pipes.
•
Exposed pipe work between the solar storage tank and the penetrations through the roofing material
should be kept to a minimum to maintain the aesthetics of the installation.
INSTALLATION CHECK LIST
Once the installation is completed and before the system is full of water, it is important to check the following:
•
The solar hot and solar cold pipes grade downwards with a continuous fall of not less than 10° from the
solar storage tank to the solar collectors. If in doubt use a spirit level.
•
On a pitched roof installation without a frame;
the right hand outlet side of the collector array is between,
◼
12 – 15 mm (for one solar collector), or
➢
24 – 30 mm (for two solar collectors)
➢
higher up the roof from the horizontal than the left hand end of the collector rail at the inlet side of the
solar collectors. If in doubt use a spirit level.
•
On a frame installation, depending upon the positioning of the frame on the roof and any minor fall the
roof may have, ensure the collector rail is either horizontal or is higher on the hot outlet side of the solar
collectors. If in doubt use a spirit level.
